Enabling scalarized conditional stores in the loop vectorizer
Hi Michael,
Thanks for testing this on your benchmarks and target. I think the results
will help guide the direction we go. I tested the feature with spec2k/2k6
on AArch64/Kryo and saw minor performance swings, aside from a large (30%)
improvement in spec2k6/libquantum. The primary loop in that benchmark has a
conditional store, so I expected it to benefit.
Regarding the cost model, I think the vectorizer's modeling of the
conditional stores is good. We could potenti...

Enabling scalarized conditional stores in the loop vectorizer
Conceptually speaking, I think we really ought to enable this.
Practically, I'm going to test it on our benchmarks (on x86), and see if we
have any regressions - this seems like a fairly major change.
Re targets - let's see where we stand w.r.t regressions first. What kind of
performance testing have you already run on this? Do you know of specific
targets where the cost model is known to

Enable vectorizer-maximize-bandwidth by default?
Hi,
I'm proposing to make vectorizer-maximize-bandwidth on by default for loop
vectorizer because it should generally help performance.
I've tested the performance impact on Intel sandybridge machine with
speccpu benchmarks:
